The Influence of Geometry on Failure Modes of Countersunk Bolted Hybrid Joints

This paper presents a numerical study for the influence of geometry on the damage initiation and growth in the CFRP (Carbon Fiber Reinforced Polymer) laminated plate of the hybrid metal-composite countersunk bolted joints. A detailed 3D finite element model incorporating material and friction-based contact full nonlinearities is developed to investigate the geometry effects on the failure modes of the hybrid metal-composite bolted joints.
